Multifunctional Control of On-chip Generated Photons by a Single Collective Mode in Monolithically Integrated All-Dielectric Scalable Optical Circuits

Recently we proposed the use of a single collective Mie mode of coupled dielectric resonators arranged in metastructures designed to simultaneously enhance the emission rate, control the direction, and propagation of emitted photons from an embedded single photon source (SPS) [J. Opt. Soc. Am. B 33(12), 2414(2016); J. Appl. Phys.120, 243103(2016)]. Here we extend the analysis to include the necessary additional two functions of beam splitting and controlled combing of photons from two distinct on-chip sources for interference. Thus, the same single Mie mode of the designed system provides all the required five functions in different spatial regions of an on-chip integrated optical circuit, enabling full control over photon interference for classical and quantum optical information processing. Single photon source architectures suited for such on-chip scalable integration are discussed.
